Re: Rule number 0
since for web & email Linux is just fine
So you've found a Linux killer app that fully replaces MS Office Outlook? suggest you share...
"...you can dual-boot with Windows configured for no network, ... or you can run Windows in a VM that has no Internet connections"
I think what is missing is the Linux version of "Blue Pill":
"The idea behind Blue Pill is simple: your operating system swallows the Blue Pill and it awakes inside the Matrix controlled by the ultra thin Blue Pill hypervisor. " [Joanna Rutkowska]
This would enable your typical user to buy a PC with Windows pre-installed.
Insert "Blue Pill" Linux install 'disk'.
"Blue Pill" proceeds to wrap Windows installation into a VM and installs Linux underneath...
